Agent Skills: premortem

Run a premortem on any plan, launch, product, hire, pricing change, strategy, or high-stakes decision. Uses Gary Klein's prospective-hindsight method — assume it already failed at a future date and work backward to surface every plan-specific cause, then produce a revised plan, mitigations, early-warning signals, and a pre-launch checklist. USE WHEN premortem this, run a premortem, what could kill this, future-proof this, stress test this plan, what am I missing here, find the blind spots, what could go wrong, am I missing anything, poke holes in this, where will this break, before I commit to this. NOT FOR adversarial attack on an arbitrary idea or argument (use RedTeam), current-state multi-perspective debate (use Council), network/system vulnerability testing (use Security), or simple feedback/factual questions. DO trigger when someone has a concrete plan or commitment where the cost of being wrong is high and the decision is still changeable.
